Remember sleeping at grandmas house and listening to the fan hum in the background?  That cool breeze that would come and go in the just the right motion to put you to sleep.  Take time to go back and fall into that deep childhood slumber...

Take a trip with us to the wilderness where we have a campfire built to warm us up before turning in for the night.  Zip up the sleeping bag and listen to the campfire and crickets with brown noise in the background.

Remember the last time you went to the beach?  You spent all day enjoying the sun, sand and ocean.  It's now the end of the day and you're tired, the sound of the waves from the balcony is the lullaby you needed.  Slip under the cool covers and enjoy reliving that memory. 

Grey noise is slightly different from white noise because it has all frequencies at equal loudness rather than equal energy.

Take a journey to the backcountry where that mountain stream is always flowing.  Enjoy the brown noise overlayed on the sounds of a mountain stream to really take the stress off.

Blue noise focuses on higher frequencies and sometimes described as water sounds.
